Description

Band strengthens cord
Invention field
The present invention relates to a kind of band to strengthen cord, its formed positioned at the tyre surface of automobile tire used in the car and Band enhancement layer between belt package, and improve the high speed performance of tire.
Background of invention
Present in the riding vehicle radial used at present in belt package, at least two cross belts be present Layer, and the fabric band enhancement layer along the circumferencial direction spiral winding with beam.Cross belt layer comprising steel cord provides Transverse direction and peripherical rigidity needed for tyre performance.The effect of band is to reduce tire caused by the centrifugal force as caused by high speed The tire increase of diameter, and the motion of the scaling between the belt outside the growth is reduced, so as to avoid belt edge point From raising tyre performance.
In a dynamic condition, the radial pressure (restraining force) applied by the band in belt package can improve tire Performance.Make the modulus and thermal shrinkage force that effective two key characters of the power are textile cords at service temperatures.Can be with Nylon 6.6, polyester (PET) and aromatic polyamides/nylon mixing cord are provided as the reinforcement in the application of current band The example of type.In nylon 6.6 strengthens cord application, cord is wrapped in steel belt package made of nylon 6.6, As yarn and the individual layer or bilayer of cord structure, according to the speed class of tire, such as 940x1,1400x1,940x2, 1400x2,1880x2 and 2100x1 so that 0-5 ° of angle is formed between face under the line, and as single tyre cord or by multiple The band (strip) that parallel cord is formed, cover entirely band beam width.When using nylon 6.6, when temperature raises at high speeds Cord modulus reduces, and thermal shrinkage force increase, therefore can compensate the difference caused by modulus declines.In addition, with height Fatigue resistance and the polymer is caused to be generally preferred as band and strengthen with the nylon 6.6 of the excellent adhesion of elastomeric material Layer.
In high-speed tire, when using the nylon 6.6 of symmetrical 940x2 structures, in order to not increase by more than two layers of layer Number, cord density (epdm, the cord quantity in 10 centimetres) increase.In several circumstances, this density increases up to 160 epdm.In this case, rivet (rivet) area reduces, therefore the rubber osmosis between cord becomes difficult.
Alternatively, when using the nylon 6.6 of symmetrical 1400x2 structures in high-speed tire, total thickness Degree depends on cord thickness and increased, and the increase of thickness causes tire weight to increase.Meanwhile the rolling resistance of tire depends on Increase in increased rubber mass.The increase of tire weight and the increase of rolling resistance cause more fuel consumptions.
Polyester as one of the reinforcement type applied for current band can be used for forming hat due to its high-modulus Belt enhancement layer, particularly in different structures.Especially, due to its high-modulus, polyethylene terephthalate (PET) May be preferable in different structures.However, PET modulus is remarkably decreased in high temperature, and due to thermal degradation, cord is in rubber Adhesiveness on glue reduces.In addition, relative to nylon 6.6, PET bendings under compression and fatigue resistance much weaker.
Another band reinforcement material used in the art, mix cord, be used for high-speed tire, this be because Individual layer is may be used as them, rivet area can keep wider, and the total amount of rubber can reduce in band enhancement layer. Further, since its initial modulus is low, it is possible to easily process, and because it has high-modulus after processing, so also Improve the high speed performance of tire.However, aromatic polyamides/nylon mixing cord is more more expensive than nylon 6.6 and PE yarn.
The advantages of band used in current techniques strengthens application and shortcoming has been explained above.In such applications, lead to Realization is crossed to reduce fuel consumption using less rubber in tire and increase the asymmetry of nylon 6.6 of the high speed resistance of tire Cord structure is not disclosed.In other words, between 1400 × 2 and 940 × 2 symmetrical cord structures of covering and corresponding to the knot The cord structure of nylon 6.6 in the space between the line density value of structure scope is not disclosed.
